Assessment and Technical Investigations The following is a summary of the assessment and technical investigations carried out on the Tuffpave 10 mm Thin Surfacing System. Page 2 of 5

3 Design Considerations 4 General 4.1 The Tuffpave 10 mm Thin Surfacing System can be designed to meet or contribute to meeting the relevant installed requirements of the MCHW, SHW, Volume 1, Series 900, Clause 942, incorporating Interim Advice Note 154/ The system is satisfactory for use on bituminous or concrete substrates, provided that they are stable and have sufficient loadbearing strength to support the loads imposed during installation and service. 4.3 Guidance on evaluating the condition of an existing surface is provided in the Design Manual for Roads and Bridges (DMRB) (1), HD 30/08, Guidance on appropriate surfacing selection is provided in the DMRB, HD 36/06, Local Authorities may have different criteria, which should be taken into consideration. (1) The DMRB is operated by the Overseeing Organisations: Highways England (HE), Transport Scotland, the Welsh Assembly Government and the Department for Regional Development (Northern Ireland). 5 Practicability of installation The system must be installed only by contractors approved by the Certificate holder, using conventional paving equipment (see the Installation part of this Certificate). 6 Surface macrotexture The system can be designed to comply with the initial and retained texture depth requirements for an installed 10 mm upper aggregate size thin surfacing system in accordance with the MCHW, SHW, Volume 1, Clause 942, incorporating Interim Advice Note 154/12, Clause 921, Table 9/3SR and Table NG 9/32, and is satisfactory for use on roads with this requirement. 7 Bond to substrate The torque bond strength of the system measured greater than 400 kpa and meets the minimum requirement of Table 5 of the Guideline Document. 8 Maintenance The system is not subject to any routine maintenance requirements. However, any damage must be repaired (see section 14). 9 Durability When installed in accordance with this Certificate, the system will provide a durable surface course for new and maintenance road construction in accordance with the MCHW, SHW, Volume 1, Series 900, Clause 942, incorporating Interim Advice Note 154/12. Installation 10 General 10.1 Application of the system, within the context of this Certificate, is carried out by installers recommended or recognised by the Certificate holder. Such an installer is a company which: employs operatives who have been trained and approved by the Certificate holder to install the system has undertaken to comply with the Certificate holder s application procedure is subject to supervision by the Certificate holder, including site inspections As part of the assessment and ongoing surveillance of the quality of installation of the system, the BBA has: agreed the quality control procedures and testing to be undertaken monitored the process and verified that it is in accordance with the documented procedures evaluated the process for management of nonconformities checked that equipment has been properly tested and calibrated undertaken to carry out the above measures on a regular basis through a surveillance process, to verify that the quality control operated is being maintained The system must be installed in accordance with the Certificate holder s installation procedures, incorporating guidance provided in BS : The system can be applied to bituminous or concrete substrates at a nominal layer thickness of between 25 mm and 50 mm on roads installed in accordance with the MCHW, SHW, Volume 1, Series 900, Clause 942. The minimum thickness at any point must not fall below 20 mm Provided that the substrate is free from standing water or ice and that the minimum rolling temperature can be achieved, the system can be installed at a minimum ambient temperature of 0 C measured on a rising thermometer.

4 11 Substrate preparation 11.1 The substrate must be prepared in accordance with BS : 2015, Section Application of the polymer-modified bitumen emulsion bond coat must ensure a minimum residual binder content of 0.35 kg m For small areas and detailing, bitumen emulsion tack coat or bond coat must be applied uniformly, using appropriate hand-held equipment The emulsion must be allowed to break (change from brown to black) prior to application of the system. 12 Laying and compaction procedures 12.1 Machine and hand installation must follow the requirements of BS : 2015, Sections 6.3, 6.4 and Compaction must follow the requirements of BS : 2015, Sections 9.2 and Rolling and compaction must be undertaken immediately after the material has emerged from the paving machine, and above the minimum rolling temperature of 100ºC. 13 Joints All joints are prepared in accordance with BS : 2015, Sections and Transverse and longitudinal cut joints must be saw cut to a full depth vertical face, cleaned, and painted with a thick uniform coating of the joint preparation material defined in section Repair Any damaged areas must be cut back to sound material by planing or other suitable means, and replaced with a material appropriate to the location, traffic levels and area of reinstatement. Materials must be selected in agreement with the Certificate holder and the purchaser. Technical Investigations 15 Tests An assessment was made of data supplied as part of installation trials and of test data to BS EN : 2006, and in accordance with the Guideline Document in relation to: texture depth wheel tracking (resistance to permanent deformation)* torque bond visual condition of system installation and performance trial (SIPT) sensitivity to water. 16 Investigations 16.1 A user/specifier survey relating to existing sites at least two years old was carried out to confirm the system s performance in use The manufacturing process was evaluated by inspection of a typical coating plant, including the methods adopted for quality control, and details were obtained of the quality and composition of the materials used Data gathered from a monitored installation trial show that, when laid at a nominal thickness of 20 mm on a road of Stress Level 1 (1) and estimated Traffic Level (2) of 613 cv/l/d, the system will meet Clause 942, Interim Advice Note 154/12, Clause 921, Table 9/3SR and Table NG 9/32 requirements for initial and retained surface macrotexture. The initial texture measured was 1.7 mm and the retained texture was 0.8 mm. (1) Site Stress Levels are defined in Interim Advice Note 154/12, Clause NG942SR Table NG 9/27. (2) Traffic Levels (cv/l/d) are defined as commercial vehicles/lane/day.
